sciencehabit writes "Here's what we know about the evolution of flight: By about 150 million years ago, the forests were filled with flying — or perhaps just gliding — dinosaurs like Archaeopteryx, possibly similar to the ancestor of modern birds. What we don't know is what primitive wings were used for before bird ancestors could fly. A new study (abstract) provides some fresh data for this debate, not from fossils but from a winged robot (video included)."
